The discovery offers evidence that some people respond to Earth’s magnetic field without knowing it. It’s not yet clear how our brains might use this information.

Why do animals see magnetic fields?

You can read all about this theory in this previous Apex article, in short, the Compass Protein Theory states that the protein-- Cry4, part of a protein class called a cryptochrome that is sensitive to blue light and helps regulate circadian rhythm, -- has been found to be the reason why certain animals are able to visualize magnetic fields. The proteins IscA1 and Cry4, when formed, are theorized to create the bond to be able to “see” Earth’s magnetic field, though this is still highly debated as humans also have magnetite -- and cannot “see” magnetic fields.

How do animals navigate?

Birds, amphibians & reptiles, and marine animals navigate by sensing changes in Earth’s magnetic field. We already know life on Earth is dependent on its magnetic field thanks to the powerful electrical currents it creates, and scientists have proven that some animals use magnetic sense, but we wanted to dig deeper into the why and how magnetic fields are so important to keep animals going where they need to go.

What is the ability of animals to migrate?

Some animal’s ability to migrate has been shown to rely on the presence of magnetism, with Earth’s magnetic fields acting as an internal GPS. This phenomenon is referred to as magnetoreception, which you can read more about the specifics in this previous blog post here.

Can humans have magnetoreception?

A study we’ve written about, originally published online in eNeuro, determined that through studying brain waves, humans can potentially have magnetoreception abilities. They found that when participants went through magnetic field rotation, distinct brain wave patterns occurred.

What is the ability of animals to sense the magnetic field?

The secrets behind magnetoreception—that is, the ability of some animals to sense Earth's magnetic field—are beginning to gradually unravel, thanks in part to a new study that demonstrates magnetic sensitivity in a completely artificial protein, which will help guide further study into what makes this phenomenon possible.

How do researchers induce magnetic sensitivity?

Researchers induced magnetic sensitivity via the radical pair mechanism by using an ' artificial protein ." In natural cryptochromes it takes a compound called a Flavin and three tryptophans, which are a type of amino acid, to create a magnetosensor, but Bialas and his colleagues created a cryptochrome-like sensor with a flavin and a single tryptophan, demonstrating the ability to "do more with less." Their artificial protein also functions at room temperature, whereas most other similar experiments are conducted in cryogenic temperatures.

Organisms as diverse as hamsters, salamanders, sparrows, rainbow trout, spiny lobsters, and bacteria all do it.

When did animals first tap into magnetic field?

One of the first concrete signs that animals can tap into the magnetic field was observed, as in many a great discovery in science, by chance. It was the fall of 1957 , and Hans Fromme, a researcher at the Frankfurt Zoological Institute in Germany, noticed that several European robins he kept in a cage were becoming restless and were fluttering up into the southwestern part of the cage. Nothing unusual there: it was known that migrating birds in cages become edgy at that time of year, and European robins in Germany migrate southwestwards to Spain to overwinter.

What made it striking that the birds were in a shuttered room?

They could see neither visual landmarks, nor their fellow, non-captive robins, nor the sun or stars, which were known to serve them as navigational aids. Clearly they were acting on something invisible, and Fromme deduced it must be the Earth's magnetic field.

How long does it take for a magnetic field to reverse?

Reversals take hundreds if not thousands of years to complete, and because for any one type of animal that represents hundreds or thousands of generations, species have time to accommodate to the change. Moreover, Kirschvink notes that even if the main dipole field were to collapse—an event that can last for up to 10,000 years during a reversal—residual fields 5 or 10 percent as strong as the main field would remain on the surface, and animals would be able to use those quite well for migration.

Where do magnetic field lines flow?

Figure 1: Magnetic field lines flow out of the South Magnetic Pole and reenter the globe at its northern end. Some creatures seem able to figure how steep the inclination angle of the field lines is at any given location and use that knowledge to aid in navigation.

Do whales follow magnetic lines?

Whales, it seems, follow these magnetic lineations during migration (see Figure 3). "If that's your game plan, and you get off track, and you follow a sharp magnetic anomaly that curves and runs into the coast, bang, you end up on the beach," says Kirschvink. Because whales are very social, if the leader makes this mistake, so does its entire pod, hence the mass strandings.

Do sea turtles have signposts?

The oceans have no signposts , but leatherbacks and other sea turtles find their way in part by tapping into our planet's magnetic field.

When did animals first sense magnetic fields?

But evidence that animals can also sense magnetic fields slowly began to mount in the mid-20 th century, led by students in Friedrich Wilhelm Merkel’s laboratory in Frankfurt, Germany. Magnetosensation was first confirmed in the European robin. (credit: F. C. Franklin via Wikimedia Commons)

What about humans?

So lots of animals possess this strange magnetic sense. What about us? Has e volution left us out of this exclusive club, or could magnetosensation be a latent power that we just don’t know we have?

How did Wiltschko change the direction of the magnetic field surrounding the birds?

Wiltschko wanted to change the direction of the magnetic field surrounding the birds and see whether they moved to a different side of the cage. Since altering the magnetic field of the Earth isn’t really an option, he used electric coils to generate a new magnetic field around the birds’ enclosure. (As you may remember from high school physics, electric current flowing in a circular loop generates a magnetic field.)

Which direction did Wiltschko change the magnetic field?

Lo and behold, Wiltschko found that when he changed the direction of the magnetic field surrounding the birds, they reoriented to whichever direction was “southwest” according to his field. They really were using magnetosensation.

Who was the scientist who discovered that humans can sense magnetic fields?

In the 1980s, a scientist at the University of Manchester, Robin Baker, decided to test whether humans could sense magnetic fields. He blindfolded a bunch of undergrads, threw them in a van, drove them miles and miles along winding roads to various unknown destinations, then asked them to point which way was home.

Can humans navigate a parking lot?

Compared to many animals, we humans are pathetic navigators. Some of us can barely navigate a parking lot.

What animals are associated with magnetotactic bacteria?

Fitak found, for the first time, that magnetotactic bacteria are associated with many animals, including a penguin species, loggerhead sea turtles, bats and Atlantic right whales.

What are some examples of bacteria that sense the magnetic field?
